Method for on-line decoking of flame cracking reactors

摘要

This invention relates to a method for on-line decoking of flame- cracking reactors whereby decoking is achieved without interruption of the normal operation of such reactors and without the necessity to change feed equipment and/or disassemble reactor components. While maintaining the temperature of the effluent at 1000° C. to 2000° C., the flow of the hydrocarbon feedstock in the reactor is periodically stopped for a time sufficient to reduce the carbon deposits to an acceptable level.
